Device for drying lifting gas for airships



Jan., Q, 1932, E. EscH DEVICE FOR DRYING LIFTING GAS FOR AIHSHPS Filed Feb. 17. `1926 llnulieutiun tiled ltehrnary it, 19%, Serial ille. 35,973, and in Germany Webruary tt, tutti.

` lll/ly invention relates to a device 'lor drying espeeially used lor initiating balloons, airshins und the lilre, and to the method ol inllating such lifting ges containers.

The intended fior use in uirships aiter its rnanulaetnre generally is stored under low pressure in large gasonieters or compressed in specinl eontainers adapted to withstand high pressure.. ln inost cases both hinds oit storage lll are utilized lor intlating uirships, especially those ot large sizes.

rlhe stored in gasorneters generally has a considerable udniizrture ot steam which duces the lifting power ol the gas. The gus ll Whit-h Was compressed does not enhibit this disarlt'untage, llllhen intlating the gas cells oil un uirship large tubes are 'utilized .tor the purpose el .avoiding great gas Velocity. Vlhe w compressed ges usually astored under a presk Wl sure et l5@ atmospheres 1s led into these tubes and passes through en expansion nozzle. ln `einenndfuig the gas cools down and withdraws heat Jtroni. 'the surrounding nozzle and the gas surrounding it. i.

N According to invention this cooling ellect is utilised For the purpose out reducing the temperature oi the gas which 'was stored in a gasoineter thereby condensing part ol the u? steam oontained` therein. To this end the lll eirpansion noeeleis situated inside ot the large tubes lending trono the gasonieter to the gas cells so that the highly compressed gas expanding through the nozzle withdraws heat it'roin the surrounding gas'coniing from the gasorneter. rlhe Water condensed in this Way :muy he caught in special devices arranged ior purpose. llt may be adriseble to adda system of eenling tubes behind the nozzle inside ot the large tubes thereby increasing the cooling elleet the enpanding gos on the surrounding llso an expansion engine may be inserted in the 'pipes leading '.lroni'the containers oi the compressed gas to the espoir nosele. ln this enpnnsion engine the terno l erature will elreadj/ be cooled down and s rnecliunieul energy may he derived thererroini.

lriuring einen a general description ci my in rention l new riant to point it out more in detail referring to the drawing vwhich represents an example embodying my invention.

The figure is a longitudinal section through a part or the tubing leading from the gasoineter to the gas cell showing the arrangement 55 for admiring compressed gas.

rlhe Wide tube l leads the 10W-pressure gas from a gasometer ll in the direction ot arrow 2. Compressed gas is led from compression tank or container 12, into a tube 3 in the direc tion of arrow d. lt first passes through turbine 5 expanding therein and developing rneehnnical energy Which may he used for any purpose.. At the same time this gas cools down and then is led through tube 6 into 5 `tube l., there passing through nozzle l und again expanding as it enters one end ot a system ci" cooling coils 8 connected to the nozrle 7. At the other end et the coil the iorrnerly compressed gas enters the tube 1 where "im it mines with the low-pressure gas and is led in the direction of arrows 9 to the gas cell i3 that is to be inflated. A special device l() is provided for the purpose ot collecting the Water condensed from ythe, 10W-pressure l do not Want to be limited to the details described or shown in the drawing, as many Variations will occur to those skilled in the art.
